Abstract

A TRACTOR AMPHIBIA contains a hermetic housing, a power installation with a cooling system, a towing winch placed in the cut-out of the hull and supplied with a casing completed with a ventilation hole and an overlap of the cooling system, communicating with the exhaust path of the cooling tower, connected to the exhaust port and the overlap of the cooling port, which communicates with the exhaust system of the cooling tower, which connects with the exhaust port and the overlap of the cooling system, which communicates with the exhaust path of the cooling system, with the outlet and the overlap of the cooling system, which communicates with the exhaust path of the cooling tower, which has an overlap of the cooling system and communicates with the exhaust system of the cooling tower, which connects to the exhaust path of the cooling system that communicates with the exhaust tract of the cooling system, which has an overlap of the cooling system, communicating with the exhaust path of the cooling system, the outlet is blocked by a lid that communicates with the exhaust tract of the cooling system, the outlet is blocked by a lid that communicates with the exhaust system of the cooling system, the outlet is blocked by a lid that communicates with the exhaust tract of the cooling system. In order to improve the thermal regime of the power plant when driving through water, an opening is made in the lower part of the front wall of the casing, which is limited to the tractor body below and to the back of the screen, which is connected to the said body, and the ventilation holes are made in the front and the top walls of the casing in the zone bounded by the wave-reflecting screen, and there is an i-tray at the casing, which is made with sockets.

Description

 7 of FIG. one .

  . ;

The invention relates to transport vehicles for moving and towing cargo by water and land, equipped with power plants and technological equipment.

The aim of the invention is to improve the thermal regime of the power plant when driving through water.

FIG. 1 shows schematically an amphibious tractor; in fig. 2 - winch casing, incision; in fig. 3 - winch at removal of gear, axonometric view.

The amphibian tractor contains a hermetic housing 1 with engines 2, a power unit 3, and air intakes. 4, a winch 5 installed in the cutout of the hull T. The winch is covered with a protective casing 6 with a folding bracket 7. In the front wall of the tractor, the casing wall, in the lower part of it, has an opening 8, and in the upper opening 9, which are made and in the front upper part of the casing 6. Fixed inside the casing; and a wave-reflecting screen 10, closing the space under the casing to the height of the opening 8. Under the winch drum there is a trough-shaped open at the top. A pallet 11, limiting the transverse movements of the cable 12. The pallet has a double bottom,. from the top 13 and bottom 14 parts. The inner cavity of the pallet 11, enclosed between the double bottom portions 13 and 14, communicates through an opening 15, made in the upper part 13, with the space under the casing 6 and through nozzles 16 with openings, made in the sides of the tractor. Casing 6 is equipped with an opening 17 for a cable 12, overlapped with an elastic visor.

Amphibious tractor works as follows,. ,

When towing, for example, pontoons with an amphibious tractor under conditions

31 i

slight disturbance the cover 7 of the casing 6- winch 5 is open. Popadak cie through the open hatch into the housing 6 sprays and sediments flow along the bottom 13

pallet to deck. Due to the inclination of the tractor, part of the water may be moved back from the deck into the tray 11. In this case, the water flows through the hole 15 to the second bottom 14

and runs down pipe 16 overboard. The air intake through the air intake 4 by the fan of the power plant 3 AECD50S cools the water and oil in the radiator and, through the flow of the winch 5,

freely comes out of the casing 6. When working on a wave in an amphibious tractor close all openings through which water could get into the hull 1, including the cover 7. At the same time

cable 12 passes through the hole

17 in the housing 6, covered with an elastic visor. The exhaust air from the housing 1 rises, filling the space under the casing 6,

and out of it through the opening 8 and the holes 9. Waves, whose height exceeds the height of the amphchbia tract, covered the casing 6 of the winch 5, are broken against it, and water through the holes 9 flows overboard.

When a wave rolls across the deck of an amphibious tractor, water is held up, screen 10. and, reflecting on it, it falls back onto the deck, the stack overboard. Water entering the pallet 11 through the opening 17 flows through the holes 15 to the bottom bottom 14 and further overboard through the nozzle 16.

The use of the present invention will improve the shipping qualities of an amphibious tractor due to the removal of water falling under the winch casing and ensuring free air flow through the holes in the winch casing.

Claims (1)

TRACTOR-AMPHIBIA, comprising a sealed enclosure, a power unit with a cooling system, a towing winch located in the cutout of the housing and equipped with a casing made with ventilation holes and a cover that is blocked by the lid, communicating with the exhaust tract of the cooling system, distinguishing it by the fact that in order to improve the thermal regime of the power plant when moving on water, an opening is made in the lower part of the front wall of the casing, which is bounded from below by the tractor body, and in the rear part by a wave-reflecting screen, which is connected n with the specified case, and the ventilation holes are made in the front and upper walls of the casing in the area limited by the wave-reflecting screen, and in the casing there is a cable guide pallet that is made with drain holes. t '1196331
